Python实现字符串移动，（将一串字符串移动几位，ABC移动一位变成BCA）

def right_shift(str_shift,shift_count):
str_to_move = “”
for i in range(shift_count):
head_str = str_shift[0]
tail_str = str_shift[1:len(str_shift)]
str_shift = tail_str + head_str

print("str_shift content is ::::::",str_shift)

def right_shift_array(str_array,shift_count):
for i in range(shift_count):
head_item = str_array[0]
str_array.remove(head_item)
str_array.append(head_item)

str_move = “abcdfg”
right_shift(str_move,2)
print(“str_move content is :::::::”,str_move)

item_array = [‘a’,‘b’,‘c’,‘d’]
right_shift_array(item_array,3)
print(item_array)
